Cisco talks up products to /slow access/ 157

Posted by Hemos from the you-can't-handle-the-truth dept.
Marc Merlin writes "This excerpt from Yahoo News tells it all:
(...) But according to marketing materials from Cisco Systems Inc. (Nasdaq:CSCO - news), the No. 1 maker of computer networking equipment, cable companies will be able to work behind the scenes with sophisticated software included in Cisco products to slow down and limit access to selected Web sites. " As you would imagine, this has got the hackles of consumer groups up-Cisco brochures are saying that this stuff would allow cable companies to make competing sites appear more slowly then preferred ones. I'm speechless.

    It is obvious that this is the way things are
    going. A company that controls the bandwidth
    can do what they want with it. I'm sure that
    the larger ISP's already do this to a certain
    extent with route selection. This just takes
    it to the next level - a single router being
    able to cause the slowdown.

    Some more related things that will happen:

    Original poster here. I should get off my ass and get an account.

    I don't know the financials. I have never been involved in the provisioning or costing side of the circuit game while working at ISPs. I do know that you get a tariffed price of X dollars per circuit if you are providing clear pipe access, I think both from the local (or competitive) exchange carrier and the long-haul carrier. This applies to your customer aggregation circuits as well as your backbone pipes, afaik. Anyone who could enlighten further would be appreciated. You don't get that price if you filter access in any way. That's been the debate with newsgroups, too, because ISPs who want to filter alt.sex.littlekids are worried that they'll lose the tariff price if they do.

    As long as this is the case, unrestricted net access is most profitable, because your backbone and aggregation circuits are cheap.

    The mention of DSL and other technologies is used as a reference point to compare services. If I can get a clear connection that allows me to do whatever I want with my circuit (I have 384k SDSL) I will pay for it, even if some guy wants to sell me RoadRunner instead. It's a buyer's market.

    I currently get my DSL from Concentric Networks, 'cuz I like their backbone better than Bell Atlantic's. My phone service is from Bell Atlantic, and my cable comes from Media One. If Media One offered me phone and cable for cheaper than BAT phone and Media One cable, I'd use that. If they offered me restricted cable modem net access on top of that, i'd tell them to piss off.

    We should be arguing for choice in high-speed net access, rather than trying to villify one service because of their policies. For all I know, there are parents out there who would love to have 'net access that filtered questionable material without them having to use some additional software. Fine. Not me. As long as I have a choice, I'm happy.

  • George, you need to get a clue (Score:1)

    Ok let's examine George's argument: The government should break up Cisco because I think they are too big. He doesn't support his argument at all. I think if you asked him why, the argument would go something like this: "Why should the government break up Cisco?" "Because I said so."

    I'm curious to hear what George's qualifications are. I work on the Internet team at a major corporation and can say that we do the same thing using software and a proxy server that the Cisco hardware can do. All major companies do. And they've been doing it for years.

    Now you might say that that is a business and that inappropriate sites need to be blocked from businesses because they reduce productivity. But you know what? Lots of AOLs web traffic is buffered at proxy servers. They could do the same thing using software that Cisco hardware does. Cable providers could do it to. Most people wouldn't know the difference. And they all could be blocking and controlling traffic right now.

    The people from the advocacy groups mention that this is a monopolization of the Internet by the cable companies, and they blame Cisco. Notice none of them are mentioning the ISP that blocks the "adult" web sites and practices filtering on it's end. Granted that consumers can choose not to use this service but the point remains that it still restricts the "open" Internet.

    But the fact is that this is a common capability. If you want to break up Cisco for doing this, attack these as well:

    • Secure Computing (Smartfilter blocking software)
    • Wavecrest Computing (ProxyReporter blocking software)
    • Netscape (their proxy server allows blocking)
    • Microsoft (see the note about Netscape Proxy)
    • Any other company that makes blocking or monitoring software.

    As you can see, Cisco isn't the only one doing this. And to blame them is to skirt the real issue. That issue is your ISP. If your ISP is blocking and you didn't tell them to, then tha'ts their fault. Cisco and all the other companies that provide blocking (with hardware or software) are providing a tool. If a company abuses it, your issue is with the abuser, not the maker of the tool.

  • The technology's morally neutral - for example, CAR is used to limit bandwidth consumed by Smurf attacks (presumably a good thing), but this same technology is (or could be) used to limit bandwidth to certain unaffiliated websites.

    This is not really very different morally to using firewalls and access lists - you can use them to block access to certain websites (probably bad) or to block access by crackers to your domain (probably good, unless you are a cracker :).
  • 'Ethically questionable'... OK, how about if the same bandwidth limits are used to ensure that one cable modem user doesn't consume all the available bandwidth for 200 homes on a given segment? To make this pointed, what if this bandwidth limitation makes it possible for VoIP packets carrying an emergency services (911, 112) call to be carried over the same net? (I know people won't use cable phones for emergencies, it's a hypothetical example!)

    The point is that quality of service and class of service technology can be used to guarantee or to limit bandwidth to or from any IP address, with any IP protocol or TCP/UDP port, etc - it's down to the user of these features (and your perspective and values of course) as to whether the resulting effect is morally good or bad.

    Astonishingly, this is exactly like IP itself, which can carry hate material just as easily as charity donations...
  • IPv4 was standardised in RFC 791, which defines 6 bits of priority information (3 bits precedence, 3 bits type of service) in what was known as the TOS byte, and is becoming known as the DiffServ field.

    IPv6 is renaming this field to Traffic Class, I think, but adding no new features - DiffServ will work fine on IPv6 as well. The only new QoS feature in IPv6, IMO, is the Flow Label, which is a longer field used to quickly classify individual flows (e.g. a VoIP call) in RSVP (which is a finer-grained way of requesting absolute bandwidth/latency, rather than just 'better treatment' a la DiffServ.)

    Some links on QoS and DiffServ:
    - Linux-DiffServ - working code for 2.2+ kernels:
    http://lrcwww.epfl.ch/linux-diffserv/
    - QoS Forum - general information: http://www.qosforum.com/
    - Orchestream Links page - http://www.orchestream.com - has links on RSVP, DiffServ, etc.
  • Cisco would be within their rights to charge for the features - as it happens, they don't. QoS features have been around in Cisco's for quite a few years. It's just that they're a touch hard to configure correctly by hand, particularly in a large network.

    Limits have the great advantage that you only need to limit in one place, whereas guarantees need to be done end to end.

  • No this is nothing like that...

    Traffic shaping is part of the protocol, and is sometimes necessary. Cisco is merely utalizing sleazy marketing tactics to pawn off this feature for all the wrong reasons. There has never been anything to stop people from doing this in the past, except that they were ignorant to the fact that it could be done.

  • From another ISP, it sounds like they are talking about the Cisco NetFlow software. This software is used to have more fine-grained control of a large network. It allows you to see what areas of the Internet are sending/receiving most of your data, and allows you to change the routing to what looks like sub-optimal, but is actually better. Shaping traffic on a per-flow basis is actually a very processor intensive process, so most companies would rather use controlled congestion...

  • A company that controls the bandwidth can do what they want with it.

    Sure, for as long as they're in business.
  • And the phrase is, "... give me liberty or give me death!"

  • Let's get email address & voicemails & start the 'Ol /. effect !
  • Dang...someone beat me to the reality check.

    To add just a bit to this point...you can do the same thing with just about any product...its not just Cisco...and since we have a significant Linux leaning here, you can even do the same in Linux. The latest incarnation is called Class Based Queuing I believe. You also might see some of the same features listed as Traffic Shaping (Packeteer has been doing this for a *long* time), and there's probably some other names that I'm forgetting.

    I do think (from what I've seen..haven't seen the actual press release) that Cisco's Marketing department hosed this one up, but the technology is just a tool, and just like a hammer is a tool, it can be used for good (building a house for the homeless) or evil (bashing in someone's skull).

    This very same tool that Cisco is talking about and everyone is up in arms about is also being used by many ISPs to prevent ICMP ping floods or SYN attacks and the like from killing connections. This very same tool that can be used for anti-competitive purposes can also be used to prevent abuses.

  • Keep in mind that bandwidth isn't free. Without the ability to manage QoS you have a situation where the greedy can make things bad for everyone else.

    This becomes a real issue when you are looking at high bitrate datastreams like streaming video. At todays prices, high quality video over the net is prohibitively expensive (8 mbs for TV quality high action video is not cheap).

    That sort of backbone bandwidth can't be had for the price of a cable-modem connection, yet cable modem providers may want to offer such services. To do so at a price point that is affordable, they have to build local caching&reflection for the content, to keep traffic off their backbone connection.

    The final peice is to allow high bandwidth streams between customers and distribution centers, where costs are well controlled, and disallow it between customers and the iternet at large.

    If you don't like it, don't get a cable modem. Hell, if you don't like it, build your own local and global fibernetwork and give away access. If you can find a way to make it work, I will gladly contribute my time to making it happen.
  • Long distance telcos have done something along these lines: they used to (maybe still do) block access to a competitors 1-800 number for calling card calls. It just goes to show that when companies get too much control they end up as parasites (e.g. insurance companies) and cease to earn their profits.
  • The last time I checked, Cisco was sucessful, partly because they do a good job of meeting the needs of their customers.

    I plan to direct my anger at the people who choose to use these features, not the people that build the tools.
  • first off, who the hell said that the FCC was going to break up CISCO??? this was about the cable operators....

    anyway, Cisco is just implementing a feature than *nix (or at least Linux) has had for a while, the ability to favor some traffic over another... this is prefectly legitimate, even though it COULD be abused... (which is the point of the Consumer groups, that without open access, the cable companies will have vast content-control powers...)

    I am about to move into a house with some friends, we plan to use QoS to make sure that some more important services do not get interrupted by web-surfing, and to make sure that every one gets AT LEAST their fair share of the bandwidth (as much as available, but no less than X)

    (yes we have enough bandwidth to care ;-)
  • ????

    the consumer groups are talking about open access re: cable...

    QoS is not a prob unless it is coupled with a monopoly in the inet access department...

  • Yeah, Lucent just bought some new company called Nexabit networks, they make routers that can move 1.4 terabits per second. Lucent is about to jump over cisco in terms of speed.
  • The last paragraph of the item noted that you can use the technique of fast access to your site / slow access to your competitor's in order to "encourage" adoption of your own service.

    Hmm. This makes me think of all the times that I've pulled up a banner-infested page only to spend 15 seconds reading the ads while the rest of the page loads.

  • This is nuthing like that
    Its more like ford installing emp guns in all there new cars and shooting an emp at all passing chryslers.

  • The NOC for an ISP recommends using traceroute to troubleshoot a users connection ?

    You wouldn't care to name that ISP so I can make damn sure I never touch them with a shitty stick would you ?
  • As stated elsewhere, this software has been available for a while, and can actually be very useful. QoS enables you to guarantee a particular information rate for a connection. For videoconferencing and other real time activities this is essential.

    As for the 'finding the optimal path' BGP4 ( the routing protocol used on most of the Internet ) doesn't select routes depending on the speed or available bandwidth of a particular route...

  • Very good analogy, bar the fact it's utter shite.

    If Cisco did charge extra for the QoS / Bandwidth Allocation then they'd be charging for an extra feature. Quite common, apparently...
  • OK.

    A customer says they're getting lousy routing to www.imvs.com

    Traceroute to www.imvs.com and tell me what you see.

    Then tell me if there is a problem with PSI or if www.imvs.com is dead, or, *shock horror* ICMP packets are simply dropped, congestion or not, thus rendering traceroute worse than useless because it has no reported a 'problem' that doesn't exist.

    Same applies to microsoft.com, news.com and many, many others because their routers and servers have got better things to do than respond to thousands of pings from DIY troubleshooters picking common addresses to 'test' their routing.
  • OK, so if I am Sprint and I configure my routers to throttle ICMP packets how does traceroute help ?

    Or if the target site has round robin DNS, and you happen to hit a particular interface that is routed round a totally different route from the 'problem' the customer is reporting ?

    Or don't they teach you that in Helpdesk 101 ?

    Traceroute is *not* a particularly useful diagnostic tool for the Internet...
  • From an end users point of view, there's not much you can do.

    But that doesn't change the point that traceroute is not very helpful as a diagnostic tool, as it can all too easily show 'problems' that don't actually exist...

    E.g., as I mentioned above, routers that silently drop ICMP packets...
  • Isn't this pretty much the same as IPv6 having the ability to set priority levels for certain packets ? As I understand it your ISP will be able to give a higher priority to packets that originiate from certain locations...ie. customers who are paying a little extra to get better performance. Meanwhile the average schmoe gets a lower priority and spends more time waiting.

  • Actually,"Class-based queueing" is the name of one of a number of scheduling mechanisms used in QoS(Quality of service)-enabled routers. Others include Strict Priority Queueing, Weighted Round-robin etc.

    "Traffic shaping" refers to the practise of queuing traffic at originating hosts or intermediate nodes so that it is less bursty.

    it can be used for various purposes. in fact
    it works really well (I've spent the last few
    days playing with it). I'm sure other routers'
    vendors have similar features.

  • I really hate to say it, but I'm forced to think of a cartoon from "Bloom County" some years back, where Opus the penguin is trying to book a flight to Cleveland or some such, and the person on the phone from Megacorp Airways (something like that) is extremely rude and demands $2000 for the ticket. So Opus gets steamed, calls a competitor, and the same person answers the phone...'cos Megacorp bought 'em all out. And btw the price is now $3000. And say "please", poophead.

    I can't help but think that once one ISP starts doing this, they all will follow, just because of the old lemming instinct--they would perceive their competitors using this Cisco garbage as having an "advantage" and would want it also. Even though AT&T claims they won't use it, it's probably only a matter of time.

  • QoS/CoS are used to provide better service to certain classes of applications or certain users.

    This kind of technology is required fo quite a few technologies to work well. VoIP, streaming audio/video.

    It is not an evil technolog. QoS is in linux, windows2000, most routers, many switches. This technology is vital to the growth of the net.

    This technology will let you say: I want to pay an extra $20 a month and get better service across your backbone. Or I want my quake traffic to have priority over my email. Or I want to dedicate 128k of this cable modem link to this video stream.

    This does mean the net becomes unfair. Too bad. It's unfair now. If you connect to UUnet, you can get access to content not available elsewhere. AOL? same thing, @Home? yep. As an Epoch customer I can't access that @home content. Oh well.

  • Just think how many of your packets go through Cisco routers. They may not be the only game in town but given the nature of the Internet, they get involved in some way. Time to think about opensource routers too, although proving reliability will be a challenge.

Worse, people would then buy the homes owned by the 150 expired folks, and then you'd have to start all over again. I recommend you just ring up your local bandwidth reseller and get your own T1 line; it's a lot cheaper and 100% foolproof to boot.

    Of course there are always a few other suggestions:

    - Find 150 gorgeous blondes and have them seduce the householders when you want to surf the net.

    - Convince all the householders that the net is a horrible, dangerous swamp filled with pornography and bomb-making information. Unfortunately, that would probably backfire in a big way, as your neighbors would promptly go on the net and look for that stuff.

    - Convince the television networks to hold the Super Bowl 365 days a year.

    On the whole, though, if you want $ 1,500 a month worth of access, the bottom line is you have to pay for it :-(.

  • Using a tunnel like this will NOT, I repeat, will NOT tell you whether or not your ISP is throttling back your traffic. The route that traffic takes from point A to point B may have nothing in common with the route from point C to point B. In other words, you may have the following situation:

    route from A -> B sucks
    route from C -> B is good
    route from A -> C is good.

    This is probably more common than people think. There are a handful of places on the Internet backbone which tend to get really clogged up. If your traffic happens to be going thru one of those points, your connection will suck. By using a tunnel to somewhere else, you may be avoiding that bottleneck and your connection will improve.

    I actually ran into exactly this scenario last night. I am a USWest.net customer, and was connecting to a host on QWest. The connection was horrible, and a traceroute showed a long tortuous path thru a half a dozen providers (Hopefully now that QWest owns USWest they will begin peering ;-). Just for kicks, I connected to work, which is a nice clean route thru USWest, BBN, and C&W. At work, we have a QWest connection in addition to a C&W connection, so from work to any QWest host was a clean route. So, by "tunneling" thru my workplace, I was able to get much better connectivity than by going directly.

    If you actually wanted determine whether or not your ISP was throttling traffic, you would have to take direct measurements. I'm not sure what the best way to do this would be, as it would depend on exactly how the ISP implemented it. Some software along the lines of traceroute or mtr might be modified pretty easily to take some measurements. Another possible approach would be to use forged TCP packets. Say you have host A using the ISP you think is throttling. You have access to another host B at a different ISP. A program on host B sends forged TCP packets that appear to be from various web sites to host A. On host A, you have a program which tallies up the received forged packets. Since all the packets are taking the same route, the packet loss rate should be the same no matter what the source address is. If the ISP is throttling, it should be pretty obvious. The one problem with this approach is that the ISP host B is connected to should be dropping the forged packets. Not that it isn't easy to find an ignorant or irresponsible ISP that will let you source forged packets...

  • As the original article states, this technology is not limited just to cable modem access. It can be used by any ISP using any access method (cable, DSL, dial-up, satellite).

    Give this information to anyone and everyone that currently has or is thinking about getting internet access. Educate them about the alternatives. We need to make the providers understand that the public *will* switch to alternate access methods if this type of system gets implemented. Last, but not least, don't let this issue die without making sure that the ISPs understand that the public knows what they are up to.

    Speaking as the owner of an ISP, restricting access doesn't work as either tactics OR strategy. What makes Internet access valuable is access to ALL sites on ALL networks. If you try to restrict access at your router (which has been suggested by some lawmakers in order to limit minors' access to pornography) you begin to lose customers.

    Where the ability to throttle becomes useful, at least as far as the ISP is concerned, is where it gives you the ability to sell metered service to co-locations (and other downstreams.) If you don't throttle, you have to sell access to your LAN as if everyone was using all of your DS3. (Assuming you have a DS3.) Throttling allows you to sell cheaper access to lower-bandwidth sites. That lowers your up-front price and allows you to sell to a bigger market with less risk.

    Oh, and don't hold your breath on that 100 Mb/s access. It remains to be seen how long it'll take the current backbone structures to adapt to the current crop of high-speed access schemes.

  • That's bull; access to the internet is access to the internet. You don't (and can't) sue when there's a network outage.

    More to the point, there are a couple of valid uses for that kind of thing. First of all, ISPs in many areas of the world are forced to restrict access to sites to conform to local legislation. It's assinine but true. And it's easy to see that happening in America - the last decade of the Republican Party being a front for the Christian Coalition is more than illustrative enough.

    Second, bandwidth limiting isn't exactly a new thing - it's used to determine quality of service. As a return for tv cable monopolies, cable co's have to devote a certain amount of broadcast to the public - public access television. It's not unreasonable to see that bandwidth might be treated in the same way - registered not-for-profit sites getting an allocated chunk. Or that pornographic sites be limited to a certain chunk (a weak second best to the point above, no doubt).
  • If they claim to be an internet service provider and restrict access to any part of the internet then sue or bring charges of fraud. The internet is the whole thing. There is no right to rewrite reality.

  • Not to bring any unwanted sanity to all these wild posts, but I thing most of the people here are out of touch with reality. (More so than they should be anyway.) I work with IOS everyday, I've got stacks of routers sitting on my desk, those are my qualifications. For a good long time, IOS has had these little things called "Access Lists", you may or may not have heard of them. They "block packets" to a given "destination". /Every/ router manufacturer has this feature implemented in some form in one of there boxes.

    On a side note, prioritization of packets is a "good thing", you want VoIP/VoFR/VoATM packets as well as Video over IP/FRM/ATM packets to get out of the box and down the line as quickly as possible. Getting lagged down in a buffer waiting for some idiot to get his porn, causes all sorts of havok in RT-streams. Don't forget that.

    There is a way to prove it. If you can get access to a linux box outside of the cable network, set up a tunnel to it, and make that tunnel your default route. Compare access times w/ and w/o the tunnel to a website you ssupect them to be throttling or blocking. If the tunnel is faster in spite of the extra hops, they are throttleing the connection.

    In a related note, I discovered that Digex is silently proxying web access upstream from my provider using a prot redirector. Usually, it works OK, but some days it is overloaded and I can get faster web access thru the above mentioned tunnel.

    Yes, it is very disconcerting that Cisco has found it serves their customers to provide such ethically questionable software. And of course it will be used for all the wrong reasons. But I think they (Cisco) have forgotten one of the fundamental rules of networks -- route around the glitches and find an optimal path through the maze. Unless the entire infrastructure is owned by a single controlling entity, no cable company, ISP, ASP or telcom can permanently limit bandwidth to/from any other entity.

    Frankly I think a little overreaction would be good for this issue. Most people don't seem to care that the same people who shovel crap over TV are going to try to lock us in to the same crap through the internet. At least this will get media attention.

    I wasn't aware that ISP's are required to provide unrestricted access. Is this legally mandatted, or simply a policy of the backbone providers? Policies can change, especially when there is bigger money at stake.

    The problem with assuming that the market will force providers to allow the freedom we expect is that it assumes that unrestricted net access is the most profitable.

    That is not guaranteed! Big media is already paid billions by advertisers because they have a captive audience. What do you think is more profitable, selling real net access, or selling locked, proprietary content, loaded with ads, under the guise of net access? It is not in their interest to allow individuals the ability to publish on the net, because that is in competition with their own services.

    And don't think competition from DSL and other technologies will change this. I'm speaking generically, because the telecomm and media industries are already intertwined in this realm. ATT owns cable companies, and MediaOne is providing phone services. They'll all follow each other's lead, doing whatever makes the most money.

Maybe some people don't realize this, but QoS is not a feature specific to Cisco equipment... And as far as I am aware, traffic shaping is also a feature which is available under Linux. Yet there has been no controversy over that.

    I've known for a long time that the web sites mentioned on /. are orders of magnitude slower than the rest of the Internet. I always thought that this was to compensate for the audiences unusually long attention spans, and attention to detail. I saw this as a courtesy.

    After all, good things are worth waiting for, so when I see that 'loading' bar zip back and forth across the bottom of my browser, I know I'm in for some good reading. And every time I get that little 'no response from server' pop-up, my anticipation just builds. The best sites, by far, are the ones that allow you ample time to get a coffee - and to indulge in the comforts of a physiological break. Sites like the 'world's smallest web server' are enough to make me pee my pants, and at work that would be embarassing. So I really do appreciate the significant delay these sites provide - as a courtesy.

    So, you see, there's nothing to balk at in this new-fangled scheme. It's a value added for the customer. Sort of like PIII enabled sites.

    OK, there is going to be a massive overreaction to this story. A few sanity checks.

    Cable Modem providers must provide unrestricted access if they are to recieve the pricing schemes that ISPs get for WAN circuits. As soon as they filter access, they aren't considered an ISP per se, and have to pay much higher prices for their circuits. This will self-regulate.

    Cable modems are being treated by some providers as a LAN based technology, and the companies doing this (read Cox in Arizona) are filtering inbound access over certain ports, not allowing customers to run servers on the cable, etc. These inferior products will be edged out of the market by other technologies.

    As soon as your ISP or cable provider decides that they can control your traffic, they can do a bunch of things that people wouldn't like ... QOS metrics that prefer internal web sites to external (from the cable network) ones are already easily implementable, if not already implemented.

    The moral of the story is that if you want leased-line style unrestricted access, you can dial up, buy DSL, or get a leased line. If cable providers don't want to play in the unrestricted access ISP field, then the free market will judge if it is a good idea. Don't blame the provider of the technology, blame the provider of the service that chooses to restrict your access.

    When I left Cisco, I swore I would never attempt to teach IP routing to a clueless crowd ever again. Time to renege, I guess.

    I have not seen the marketing materials Yahoo! is talking about. But I do know what a Cisco router (and a Nortel, Bay, etc) can do. One of the things it can do is prioritize or block traffic based on source/destination pairs, protocol numbers, whether or not its SYN bit is set, whatever. What I am seeing is that people somehow find fault in a router being able to do this. I'm speechless. Depending on the drugs you were smoking at the time, you COULD find fault with Cisco Marketing playing up this feature. This, combined with the fact that cable ISPs (let's not dance semantically here, shall we) are monopolistic entities by virtue of their infrastructure ownership, can be seen as quite nefarious. But can any of you goobers actually tell me that the fact that you can filter traffic on a Cisco router is, of itself, wrong? As an ex-member of Cisco Engineering (though not speaking for them) give me a goddamm break.

    Your ISP can filter websites any time they want, by the way. The difference is that you have a choice in dial-up ISPs. You typically don't with a cable ISP, giving the latter much more leeway in the unethical things they can do.
